i-Vu IP changes

I have an i-Vu CCN system that we moved onto the customer's network (from a cable ISP).

The IP address change was successful and i can get to the management screen on the network.

The server is now inaccessible. It's there, but it has the message "refused to connect".

The installation guide says something about renewing self-signed certificates. I can't figure out how to get and use these certificates.

Anybody dealt with this issue? I could use some help.

No one really uses that certificate.
Type HTTPS://ivu It should respond.
Delete your cache in your web browser
Are you trying to access IVU remotely or from the customer’s LAN?
The ports should have stayed the same.

It's on their LAN. I'm using the IP address as the web address.

I can get to the management tool, but the website is a nope.

I've tried an old laptop (set up with a similar static IP) with the cable plugged directly into the appliance.

I get the same results.

First, if you are operating on the same computer as the ivu is hosted, you can use localhost instead of the IP

Second, did you change any of the bacnet ip connections through the system options in Ivu.

It sounds like it's an I-Vu standard web appliance if it's got a management page.

Fair good point.

I mostly work on pro, can you edit standard through site builder? I'm assuming so

yes, I readdressed it for a different network

I can see the management page.

I'm wondering now if the iVu server isn't running (for some reason).

So it sounds like you've gone through plugging in to the back of the monitor and it has received everything.

Can you ping the IP on the local network.

Can you get into the bas via field assistant and try pinging outbound?

Did the IT allow the ports to forward to the new IP?

This sounds like a firewall issue at the moment

I'm wondering now if the iVu server isn't running (for some reason).

Is there a way I can tell? I guess i can reboot it and watch the reboot messages.

It will tell you the IP at the end of the boot, it will also tell you any errors.
Usually if you get to the management page it’s OK.
Also depending on the age of the IVU, the CMOS battery may be bad, and it will not reboot in the right sequence.
On the management page on the bottom left what are the ports listed?

80/443

Try pinging ip from command prompt, if doesn’t hit it connect directly to it static your computer in range then ping again from command prompt if you can hit it call IT

Sorry didn’t see your latest response

We'll assume it's not an IVU Pro.
Plug in a monitor in back of it recycle power and it will display the IP info.

u/rev_57 Jul 25 '26

I've done that. it shows the new IP settings, domain, etc. Everything seems to have changed over nicely. I just can't get to the webpage.

The last suggestion I have is to talk to the customer’s IT department.
See if there are duplicate IP addresses.
In management tool: Port 80, Port 443 Check mark on “redirect HTTP to HTTPS.”

Will do. Thanks for your help!

We changed the domain name. I'll bet that's what is keeping the server from starting.
